This is my print_r($from); response how to do I print the "From" "Personal" part of this array to it would read "Chris Hope"??

[bradgrafelman]

Those are all basically member variables of a class, so you can access it via standard [man]oop[/man] methods; $from->from[0]->personal should do the trick.

Cheers, what about a loop for each item in a array

    [0] => stdClass Object
        (
            [personal] => 2GB SPORT
            [mailbox] => sport
            [host] => 2gb.com
        )

[1] => stdClass Object
    (
        [personal] => AAP
        [mailbox] => jancetics
        [host] => aap.com.au
    )

[2] => stdClass Object
    (
        [personal] => Adam Hamilton
        [mailbox] => hamiltona
        [host] => heraldsun.com.au
    )

How do i do this?

[bradgrafelman]

Looks like just a standard array, so just use [man]foreach/man on the array variable.

[kiwis]

echo "<To><![CDATA[";
foreach ($to as $i => $value) {
echo " " $to[0]->mailbox . "@" . $to[0]->host . ";";
}
echo "]]></To>";

This does not work though?

[bradgrafelman]

Well... that's because you didn't exactly use [man]foreach/man correctly. First, are you sure $to is the variable that contains the array you showed above? If so, then you'd do something like:

foreach($to as $data) {
    // $data is now a stdClass Object
}

[kiwis]

echo "<To><![CDATA[";
foreach ($to as $data) {
echo " " $data[0]->mailbox . "@" . $data[0]->host . ";";
}
echo "]]></To>";

Parse error: syntax error, unexpected T_VARIABLE, expecting ',' or ';' in /home/xuser/public_html/mypage.php on line 61

I know what this error is saying but can not see the issue?

[bradgrafelman]

Missing a period between the first string piece and the first variable.

Also, why did you use $data[0]? If $to is the array you showed above, then $data won't be an array - it's just an object.

[kiwis]

Sorry I worked it out

echo "<To><![CDATA[";
foreach ($to as $data) {
echo " " . $to[0]->mailbox . "@" . $to[0]->host . ";";
}
echo "]]></To>";

Problem is if there is more than one it does not work, if there is just 1 (0) then it works...

[bradgrafelman]

Do a [man]var_dump/man on the $to variable and show us its structure.

[kiwis]

It goes on longer than this but this is the dump

array(173) {
  [0]=>
  object(stdClass)#363 (3) {
    ["personal"]=>
    string(9) "2GB SPORT"
    ["mailbox"]=>
    string(5) "sport"
    ["host"]=>
    string(7) "2gb.com"
  }
  [1]=>
  object(stdClass)#259 (3) {
    ["personal"]=>
    string(3) "AAP"
    ["mailbox"]=>
    string(9) "jancetics"
    ["host"]=>
    string(10) "aap.com.au"
  }
  [2]=>
  object(stdClass)#272 (3) {
    ["personal"]=>
    string(13) "Adam Hamilton"
    ["mailbox"]=>
    string(9) "hamiltona"
    ["host"]=>
    string(16) "heraldsun.com.au"
  }
  [3]=>
  object(stdClass)#281 (3) {
    ["personal"]=>
    string(10) "Adam Hawse"
    ["mailbox"]=>
    string(6) "ahawse"
    ["host"]=>
    string(17) "networkten.com.au"
  }

[bradgrafelman]

Right, so go back to my example; the point of using [man]foreach[/man]($to as $data) is that the foreach() construct will place each array entry into $data after each iteration. It's basically a while() loop that loops through all array indexes one-by-one.

Since you still used $to inside the foreach() loop, though, you basically ignored the whole point of the foreach() statement and accessed the array directly. Instead, you should be using $data (without any array index, since $data will reference the contents of the array one-by-one, and the contents are objects).

[kiwis]

So ...

echo "<To><![CDATA[";
foreach ($to as $data) {
//foreach ($to as $i => $value) {
echo " " . $data->mailbox . "@" . $data->host . ";";
}
echo "]]></To>";

[bradgrafelman]

Based on the var_dump() above, yes, that seems right. Did it work?

[kiwis]

Yes i did, thanks so much for your help.
